too many open udp ports

[vinay dwarakanath <vindwar () yahoo com>]

Hi all,

When i port scan from inside a network and if the
proxy is on the DMZ the port scan reveals a lot of
open UDP ports. is this normal or does this mean a
security loop hole. the proxy is a MSproxy and the
scan was conducted from fscan inside the dmz. Can
anybody explain.

Pl don't mistake if this is a basic question as i am
very new to this feild.

 Regards
Vinay
